Figure 5 – Instrument Back Panel
2.3.1 Pneumatic Connections
The Serinus 60 has three pneumatic ports on the back panel of the instrument: the Sample Port , the
Calibration Port and the Exhaust Port . All tubing and fittings used should follow the instructions
below:

Must be made of Teflon® FEP material, Kynar®, stainless steel, glass or any other suitably inert
material.

Sample line should be no more than two meters in length with ⅛ inch ID and ¼ inch OD.

Sample inlet pressure should not exceed 5 kPa above ambient pressure.

Tubing must be cut squarely and any burrs removed.

Remove the inlet port nut and insert the tubing through the back of the nut with the tube
extending one inch through the front.

Place the tubing into the port until it hits the tube stop inside the fitting.

Place the nut back onto the fitting and tighten clockwise until finger tight.

Nuts should be re-tightened when instrument reaches operating temperature.
Sample Port
The sample port must be connected to an ambient source of sample air. When using a sample
manifold the Serinus requires at least 1 slpm delivered to the sample manifold (0.5 slpm for
measurement plus approximately 50 % excess).
